Nymphicus hollandicus

Also known as Weero, Quarrion, Cockatoo Parrot

Nomadic flocks sweep across the arid interior of Australia in search of fresh water and ripening grass seeds. These slender parrots use their tall, movable crests to communicate mood to flockmates, raising the feathers high when curious or alert and laying them flat when threatened. Monogamous pairs bond for life, relying on eucalyptus tree hollows near seasonal rivers to raise their chicks.
